Troubleshooting

If clock module is disabled at startup with locale::facet::_S_create_c_locale
name not valid error message try one of the following:

•   check if LC_TIME is set properly (glibc)
•   set locale to C in the config file (musl)

The locale option must be set for {calendar} to use the correct start-of-week, regardless of system locale.

  Calendar in Chinese. Alignment

In order to have aligned Chinese calendar there are some useful recommendations:

1.  Use "WenQuanYi Zen Hei Mono" which is provided in most Linux distributions
2.  Try different font sizes and find best for you. size = 9pt should be fine
3.  In case when "WenQuanYi Zen Hei Mono" font is used disable monospace font pango tag

Example of working config

    "clock": {
    	"format": "{:%H:%M}  ",
    	"format-alt": "{:%A, %B %d, %Y (%R)}  ",
    	"tooltip-format": "n<span size='9pt' font='WenQuanYi Zen Hei Mono'>{calendar}</span>",
    	"calendar": {
    		"mode"          : "year",
    		"mode-mon-col"  : 3,
    		"weeks-pos"     : "right",
    		"on-scroll"     : 1,
    		"on-click-right": "mode",
    		"format": {
    			"months":     "<span color='#ffead3'><b>{}</b></span>",
    			"days":       "<span color='#ecc6d9'><b>{}</b></span>",
    			"weeks":      "<span color='#99ffdd'><b>W{}</b></span>",
    			"weekdays":   "<span color='#ffcc66'><b>{}</b></span>",
    			"today":      "<span color='#ff6699'><b><u>{}</u></b></span>"
    		}
    	},
    	"actions": {
    		"on-click-right": "mode",
    		"on-click-forward": "tz_up",
    		"on-click-backward": "tz_down",
    		"on-scroll-up": "shift_up",
    		"on-scroll-down": "shift_down"
    	}
    },
